I've replaced the alternator and signal generator on my 1998 Suzuki Intruder VL 1500 and since it back fires like crazy and most of the time will not start or run without full choke. I'm thinking this is related to ignition timing after seeing posts on various forums about others with the same issue however while reading the Hanes manual for the bike, it states the following:
On carbureted models, the ignition system consists of a signal generator, igniter with an 8-bit microprocessor (IC), two ignition coils and two park plugs. During operation, the IC in the igniter receives input from the signal generator, throttle position sensor, and MAP sensor to determine the ignition timing for the operating conditions.
The IC sends a signal to the ignition coil, the primary winding turns off and on, and a high voltage is induced in the secondary winding, which fires the spark plug.
It says nothing there about a "distributor". Does this bike have a distributor and how can I adjust ignition timing?
